Writing in Time, Robert Johnson has a few recommendations to rescue the field of economics from its current state:
First, economists should resist overstating what they actually know. The quest for certainty, as philosopher John Dewey called it in 1929, is a dangerous temptress. In anxious times like the present, experts can gain great favor in society by offering a false resolution of uncertainty. Of course when the falseness is later unmasked as snake oil, the heroic reputation of the expert is shattered. But that tends to happen only after the damage is done.
Second, economists have to recognize the shortcomings of high-powered mathematical models, which are not substitutes for vigilant observation. Nobel laureate Kenneth Arrow saw this danger years ago when he exclaimed, “The math takes on a life of its own because the mathematics pushed toward a tendency to prove theories of mathematical, rather than scientific, interest.”

The third remedy for repairing economics is to reintroduce context. More research on economic history and evidence-based studies are needed to understand the economy and overcome the mechanistic bare-bones models the students at Harvard objected to being taught.

Fourth, we must acknowledge the intimate, inseparable relationship between politics and economics. Modern debates about who caused the financial crisis — government or the private financial sector — are almost nonsensical. We are living in an era of money politics and large powerful interests that influence the laws and regulations and their enforcement. In order to catalyze the evolution of economics, research teams would benefit from multidisciplinary interaction with politics, psychology, anthropology, sociology and history.
